Normal Starting — Diesel Engine
Before starting your vehicle, adjust your seat,
both inside and outside mirrors, and fasten
your seat belts.
The starter is allowed to crank for up to
30-second intervals. Waiting a few minutes
between such intervals will protect the
starter from overheating.NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke.
This condition will disappear as the engine
warms up.
Battery Blanket Usage
A battery loses 60% of its cranking power as
the battery temperature decreases to 0°F
(-18°C). For the same decrease in tempera -
ture, the engine requires twice as much
power to crank at the same RPM. The use of
battery blankets will greatly increase starting
capability at low temperatures. Suitable
battery blankets are available from your
authorized Mopar dealer.
Normal Starting Procedure — Keyless
Enter-N-Go
Observe the instrument panel telltales when
starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
1. Always apply the parking brake.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP
button once.
NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The
“Wait to Start” telltale will be illuminated
WARNING!
Before exiting a vehicle, always come to
a complete stop, then shift the auto-
matic transmission into PARK and apply
the parking brake.
Always make sure the keyless ignition
node is in the OFF mode, key fob is
removed from the vehicle and vehicle is
locked.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Leaving children in a vehicle unattended
is dangerous for a number of reasons. A

Auto Park Brake
The electric park brake can be programmed
to be applied automatically whenever the
vehicle is at a standstill and the automatic
transmission is placed in PARK, or with a
manual transmission, whenever the ignition
is turned “OFF”. Auto Park Brake is enabled
and disabled by customer selection through
the Customer Programmable Features
section of the Uconnect Settings.
Any single auto park brake application can
be bypassed by pushing the EPB switch to
the release position while the transmission is
placed in PARK.
WARNING!
Never use the PARK position as a substi-
tute for the parking brake. Always apply
the parking brake fully when exiting the
vehicle to guard against vehicle move-
ment and possible injury or damage.
When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock your vehicle.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
Do not leave the key fob in or near the
vehicle, (or in a location accessible to
children), and do not leave the ignition
in the ACC or ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake
when leaving your vehicle, or it may roll
and cause damage or injury. Also be
certain to leave the transmission in
PARK. Failure to do so may allow the
vehicle to roll and cause damage or
injury.

Driving the vehicle with the parking brake
engaged, or repeated use of the parking
brake to slow the vehicle may cause
serious damage to the brake system.

WARNING! (Continued) CAUTION!
If the Brake System Warning Light remains
on with the parking brake released, a
brake system malfunction is indicated.

AUTOMATIC
TRANSMISSION — IF
EQUIPPED
WARNING!
It is dangerous to shift out of PARK (P)
or NEUTRAL (N) if the engine speed is
higher than idle speed. If your foot is not
firmly pressing the brake pedal, the
vehicle could accelerate quickly forward
or in reverse. You could lose control of
the vehicle and hit someone or some-
thing. Only shift into gear when the
engine is idling normally and your foot is
firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As
with all vehicles, you should never exit a
vehicle while the engine is running.
Before exiting a vehicle, always come to
a complete stop, then apply the parking
brake, shift the transmission into PARK,
turn the engine OFF, and remove the key
fob. When the ignition is in the LOCK/
OFF (key removal) position, (or, with
Keyless Enter-N-Go, when the ignition is
in the OFF mode) the transmission is
locked in PARK, securing the vehicle
against unwanted movement.
When leaving the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
Never use the PARK position as a substi
-
tute for the parking brake. Always apply
the parking brake fully when exiting the
vehicle to guard against vehicle move-
ment and possible injury or damage.
WARNING! (Continued)
Your vehicle could move and injure you
and others if it is not in PARK. Check by
trying to move the gear selector out of
PARK with the brake pedal released.
Make sure the transmission is in PARK
before exiting the vehicle.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to
children), and do not leave the ignition
(in a vehicle equipped with Keyless
Enter-N-Go) in the ACC or ON/RUN
mode. A child could operate power
windows, other controls, or move the
vehicle.

NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the LOCK/OFF (key removal) posi -
tion. The key fob can only be removed from
the ignition when the ignition is in the LOCK/
OFF position, and the transmission is locked
in PARK whenever the ignition is in the
LOCK/OFF position.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans -
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the ignition must
be in the ON/RUN mode (engine running or
not) and the brake pedal must be pressed.
The brake pedal must also be pressed to shift
from NEUTRAL into DRIVE or REVERSE
when the vehicle is stopped or moving at low
speeds.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is
displayed both beside the gear selector and
in the instrument cluster. To select a gear
range, press the lock button on the gear
selector and move the selector rearward or
forward. You must also press the brake pedal
to shift the transmission out of PARK (or
NEUTRAL, when the vehicle is stopped or
moving at low speeds). Select the DRIVE
range for normal driving. NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects REVERSE
while driving forward), the position indicator
will blink continuously until the selector is
returned to the proper position, or the
requested shift can be completed.
The electronically-controlled transmission
adapts its shift schedule based on driver
inputs, along with environmental and road
conditions. The transmission electronics are
self-calibrating; therefore, the first few shifts
on a new vehicle may be somewhat abrupt.
This is a normal condition, and precision
shifts will develop within a few hundred
miles (kilometers).
The nine-speed transmission has been devel
-
oped to meet the needs of current and future
FWD/AWD vehicles. Software and calibration
is refined to optimize the customer’s driving
experience and fuel economy. By design,
some vehicle and driveline combinations
utilize 9th gear only in very specific driving
situations and conditions.
CAUTION!
Shift into or out of PARK or REVERSE
only after the vehicle has come to a
complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
Before shifting into any gear, make sure
your foot is firmly pressing the brake
pedal.

FOUR-WHEEL DRIVE
OPERATION
1-Speed Four-Wheel Drive (4X4) — If
Equipped
This feature provides on-demand four-wheel
drive (4X4). The system is automatic with no
driver inputs or additional driving skills
required. Under normal driving conditions,
the front wheels provide most of the traction.
If the front wheels begin to lose traction,
power is shifted automatically to the rear
wheels. The greater the front wheel traction
loss, the greater the power transfer to the
rear wheels.1-Speed 4X4 Switch Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a
pre-emptive effort to improve vehicle launch
and performance characteristics.
2-Speed Four-Wheel Drive (4x4) — If
Equipped
2-Speed 4x4 Switch
2-Speed 4x4 Switch (With Rear Lock)
The Four-Wheel Drive is fully automatic in
the normal driving mode. The Selec-Terrain
buttons provide three selectable mode posi -
tions:
4WD LOW
REAR LOCK (If Equipped)
NEUTRAL
When additional traction is required, the
4WD LOW range position can be used to
provide an additional gear reduction which
allows for increased torque to be delivered to
both the front and rear wheels. 4WD LOW is
intended for loose, slippery road surfaces
only. Driving in 4WD LOW on dry,
hard-surfaced roads may cause increased
tire wear and damage to driveline
components.
CAUTION!
All wheels must have the same size and
type tires. Unequal tire sizes must not be
used. Unequal tire size may cause failure
of the power transfer unit.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 150

151
When operating your vehicle in 4WD LOW,
the engine speed is approximately three
times that of the normal driving mode at a
given road speed. Take care not to overspeed
the engine and do not exceed 50 mph
(80 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause
damage to the driveline components.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go
faster than road conditions permit.
Shift Positions
For additional information on the appropriate
use of each 4WD system mode position, see
the information below:
NEUTRAL (N)
This range disengages the driveline from the
powertrain.
4WD LOW
This range is for low speed four-wheel drive.
It provides an additional gear reduction
which allows for increased torque to be deliv-
ered to both the front and rear wheels while
providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NOTE:
Refer to “Selec-Terrain — If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0
to 5 km/h), the ignition in the ON mode and
the engine running, shift the transmission
into NEUTRAL, and push the “4WD LOW”
button once. The “4WD LOW” indicator light
in the instrument cluster will begin to flash
and remain on solid when the shift is
complete.
2-Speed 4x4 Switch (With Rear Lock)
NOTE:
If shift conditions/interlocks are not met, a
message will flash from the instrument
cluster display with instructions on how to
complete the requested shift.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear
driveshafts from the powertrain and will
allow the vehicle to roll, even if the
automatic transmission is in PARK (P) (or
manual transmission is in gear). The
parking brake should always be applied
when the driver is not in the vehicle.

“Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for
further information.
Shifting into or out of 4WD LOW is
possible with the vehicle completely
stopped; however, difficulty may occur
due to the mating clutch teeth not being
properly aligned. Several attempts may be
required for clutch teeth alignment and
shift completion to occur. The preferred
method is with the vehicle rolling 0 to3 mph (0 to 5 km/h). If the vehicle is
moving faster than 3 mph (5 km/h), the
4WD system will not allow the shift.
NEUTRAL Shift Procedure
For the neutral shift procedure refer to
“Recreational Towing” in chapter for further
information.
Rear Electronic Locker (E-Locker) System
— If Equipped

E-Locker.

When disengaging Rear E-Locker, the indi-
cator lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain off.

Shifting into or out of Rear E-Locker is
possible with the vehicle completely
stopped; however, difficulty may occur
due to the mating clutch teeth not being
properly aligned. Several attempts may be
required for clutch teeth alignment and
shift completion to occur. The preferred
method is for the vehicle to be rolling,
below 15 mph (24 km/h), while including
right and left steering maneuvers to allow
for the clutch teeth to align.
The Rear E-Locker System must be disen -
gaged prior to taking the vehicle out of
4WD LOW range. If 4WD LOW shift condi -
tions/interlocks are not met, a message
will flash from the instrument cluster
display with instructions on how to
complete the requested shift.
SELEC-TERRAIN
Description
Selec-Terrain allows the driver to specify the
driving surface to allow the vehicle systems
to provide the best performance possible
across a wide range of conditions
Rotate the Selec-Terrain knob to select the
desired mode.
Selec-Terrain Switch
Selec-Terrain offers the following modes:
AUTO — Fully automatic, full time
four-wheel drive operation can be used
both on and off road. Balances traction
with seamless steering feel to provide
improved handling and acceleration.
SNOW — Tuning set for additional stability
in inclement weather. Use when driving on
loose traction surfaces such as snow,
while either on or off road. When in SNOW
mode (depending on certain operating
conditions), the transmission may use
SECOND gear (rather than FIRST gear)
during launches, to minimize wheel slip -
page.
SPORT — This mode alters the transmis -
sion's automatic shift schedule for sportier
driving. Upshift speeds are increased to
make full use of available engine power.
NOTE:
SPORT mode is not available when 4WD
LOW is selected.
SAND/MUD — Off-road calibration for use
on low traction surfaces such as mud,
sand, or wet grass. The 4WD system
provides maximum capability to all
wheels. Some binding may be felt on high
traction surfaces. The electronic brake
system will be adjusted to reduce the
automatic braking of slipping wheels and
to allow the engine to operate without
restriction.
